SHEET-COATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 773,840, dated November 1, 1904.

Application filed March 30, 1904:. Serial No. 200,687. (No model.)

To (LZZ 7071 07 it puny concern:

Be it known that LEUGENE \VILLIAMs, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sheet-Coating Machines, of which the following is a specification.

The present invention relates to a coating apparatus adapted for coating or painting sheets of paper and the like for sample col-orcards, and has for its object to 7 provide a simple and eflicient structural formation and combination of parts whereby the paint or other coating fluid is applied and uniformly spread over the sheet in a rapid and economical manner, all as will hereinafter more fully appear and be more particularly pointed out in the claims.

In the accompanying drawings, illustrative of the present invention, Figure l is a longitudinal sectional elevation of a coating apparatus embodying the present improvements. Fig. 2 is a detail transverse section at line a; 0, Fig. 1. Fig. 3 is an enlarged detail end elevation of the brush-carriage audits guidetrack. Fig. 4 is an enlarged detail plan of the same. Fig. 5 is an enlarged detail longitudinal section of the same at line in Fig. 3. Fig. 6 is an enlarged detail side elevation of the same.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents a horizontal table or surface upon which is laid the sheet of paper or the like to be coated.

2 is a tank arranged at one end of the. table 1 in a plane below that of said table and adapted to contain a supply of the fluid used in the coating operation.

3 is a fixed supporting yoke or bracket on the supporting-frame of the table 1, in which the tank 2 is removably supported, so that it may be removed and replaced in making a change of coating fluids.

4. is a horizontal bar or rod arranged in separated relation to an end wall of the tank 2 and near the upper end of said tank. Such bar or rod is adapted to act as a wiper in removing the surplus coating fluid from the coating-brush, hereinafter described.

represents a pair of track-rails extending lengthwise of the apparatus and arranged at opposite sides of the same and in a plane above the coating-table. Such track-rails are horizontal to the length of the coatingtable,as

shown, and are provided with downwardlycurved extensions 6 adjacent to the tank 2, for purposes hereinafter stated.

7 is a brush-carrying head arranged transversely of the apparatus and having holdingjaws at its lower end adapted to be clamped upon the head of a coating-brush.

8 is the coating-brush, having a Width approximating that of the coating-table 1 and secured to the carrying-head 7, as above described, so that its bristle portion will have proper coating contact with a sheet of material carried upon the coating-table.

9 represents end truck-plates pivotally connected to the respective ends of the brushcarrying head 7 and provided with upper sets of track-wheels 10, having rolling engagement with the upper surface of the trackrails 5, and with single centrally-arranged track-wheels 11, having rolling engagement with the under surface of said track-rails. In order to permit the free travel of the series of track-wheels 10 and 11 around the curved extensions 6 of the track-rails, this central track-wheel 1 l of each set is yieldingl y supported upon its truck-plate 9 in any usual and suitable manner, preferably,.however, in the manner shown in the drawings, in which 12 is a slide moving in a guideway in the end truck-plate 9 and carrying the journalpin or axle of a central track-Wheel 11. 13 is a spring tending to draw said slide and Wheel toward the companion pair of trackwheels 10. g

14: is a handle on the brush-carrying head 7 for the convenient manipulation of the same by'hand.

is an open-bottom blast-head of a size approximating that of the coating-table 1 and adapted to have movement in a plane above said table, so that it may be moved into a position immediately over the table or away from said table in the cycle of operations of the present apparatus. The described movement of the blast-head 15 may be attained by anyusual. and suitable supporting mechanism, preferably, however, by means of an overhead horizontal track 16, upon which a carriage 17 has movement and to which carriage the hood 15 is connected by suspension-bars 18, as illustrated in Fig. 1.

19 is a blast-pipe connecting the blast-head 15 with a suitable source of air-pressure, such as a fan-blower, and 520 is a telescopic connection in a horizontal portion of said. blastpipe to permit of the movement of the blasthood in a horizontal direction and in a rectilinear manner without breaking the connection between the stationary portion of said blast-pipe and the blast-hood.

21 represents gutters at the edges of the coating-table for receiving any overflow of the coating fluid during the operation of the apparatus and preventing the wastage of such fluid upon the floor.

In the operation of the present apparatus the operator by means of the handle 14 moves the bruslrcarrier along the inclined extension 6 of its supporting-track to effect an immersion of the bristle portion of the coating-brush 8 in the coating fluid contained in the tank 2. Owing to the pivotal connection of said brushcarrier to its truck-plates 9, the operator is enabled to swing the brush forward and backward in the coating fluid to efi'ect a proper charging of the brush, as well as to bring the brush in contact with the wiper-rod t to remove any surplus coating fluid from the brush. The operator still grasping the handle 14. brings the charged brush to the middle of the sheet to be coated as said sheet lies in a horizontal position on the coating-table and moves the brush back and forth over said sheet, so as to coat the entire surface of the same. During such manipulation a movement in a horizontal plane is imposed upon the brush and its carrying-head by the track-rails 5 and connections heretofore described between said rails and the brush-plates of said carryinghead. \Vith the completion of such fluid-applying operation the brush-carrying head is moved out of the way from over the coatingtable and the blast-head 15 brought forward over the coated sheet and the air-blast turned on to effect a very even spreading of the coating while yet fluid upon the sheet. From extended practical test it has been found that the air-blast so applied produces a very even and uniform tint over the entire surface of the sheet. ()n the completion of such spread.- ing operation the air-blast is shut off, the blast-head moved out of the Way from over the coating-table, and the coated sheet removed and replaced by a fresh sheet ready for a repetition of the above-described cycle of operations.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is
